Carbon emissions are closely related to global warming. More than 70% of carbon have been generated in cities. Many studies analyzed the effects cities on emissions, from perspective urbanization, economics, and land use, yet a detailed understanding relationship between urban form is lacking due absence reasonable set metrics. The aim this research explore through empirical research. By eliminating collinearity, we established landscape metrics comprising Class Area (CA), Mean...

China is one of the largest carbon emitting countries in world. Numerous strategies have been considered by Chinese government to mitigate emissions recent years. Accurate and timely estimation spatiotemporal variations city-level vital importance for planning low-carbon strategies. For an assessment during periods 2000–2017, we used nighttime light data as a proxy from two sources: Defense Meteorological Satellite Program’s Operational Linescan System (DMSP-OLS) Suomi National...

The primary purpose of this research is to understand those elements that define heavy metals contamination and propose a novel assessment method based on principal component analysis (PCA) in the Yangping River region Lingbao City, China. This paper makes detailed calculations regarding such factors single-factor (Pi) Nemerow's multi-factor index (PN) found surface water River. maximum values Pi (Cd) (Pb) were determined be 892.000 113.800 respectively. value PN was calculated 639.836....

This study was conducted to evaluate chemical composition, nitrogen-corrected true metabolizable energy (TMEn) and amino acids digestibility of corn distillers dried grains with solubles (DDGS) produced in China. Twenty five sources DDGS collected from 8 provinces A precision-fed rooster assay used determine TMEn 35 adult cecectomized roosters, which each sample tube fed (30 g). The average content ash, crude protein, total acid, ether extract, fiber neutral detergent were 4.81, 27.91,...

At present, extracting water-soluble organic matter (WSOM) from agricultural waste is primarily used to evaluate soil content in farmland. However, only a few studies have focused on its vertical behavior the profile. This study aims clarify three-dimensional fluorescence spectrum characteristics of WSOM samples 0-60 cm black profile before and after different chemical fertilizer treatments six years fertilization. Fluorescence spectroscopy combined with ultraviolet-visible (UV-Vis)...

The oil production of the multi-fractured horizontal wells (MFHWs) declines quickly in unconventional reservoirs due to fast depletion natural energy. Gas injection has been acknowledged as an effective method improve recovery factor from reservoirs. Hydrocarbon gas huff-n-puff becomes preferable when CO2 source is limited. However, impact complex fracture networks and well interference on EOR performance multiple MFHWs still unclear. optimal parameters are significant for enhancing...

ABSTRACT Blood testis barrier (BTB) is an important target of cadmium (Cd) toxicology, but the mechanism underlying Cd-induced impairment BTB function remains fully elucidated. The mammalian rapamycin (mTOR) complex 2 (mTOR2) regulates via its effects on cellular junctions and cytoskeleton Sertoli cells. In this study, we investigated whether mTOR2 was involved in Cd exposure integrity. A model vivo established prepubertal male rats using a single intraperitoneal injection Cadmium Chloride...

The incomplete enforcement of environmental regulations in China is a serious issue protection affairs, and this paper attempts to provide new explanation for its prevalence from the perspective strategic interaction. Under Chinese decentralization, are seen by local governments as tool compete scarce resources, which leads interactions between regions. Therefore, under theoretical framework regional policy spillovers, examines interaction behavior regulation with spatial econometric...
